Abstract:
This study deals with experimental investigation of mechanical properties of recycled coarse aggregate (RCA) concrete. The scope of the investigation programme is defined to generate detailed material properties for concrete of M25 grade made with various percentage of flyash, GGBS (Granulated blast furnace slag), recycled coarse aggregates with replacement percentage of 100, 90, 80, 70, 60, 50. The experimental programme consisted of thirty two batches of casting and testing of sustainable concrete elements in compression, tension and in flexure. The stress-strain relationship for concrete Recycled Coarse Aggregate concrete under uniaxial compression has been evaluated. The influence of replacement ratio of recycled coarse aggregate, flyash, GGBS on RCA concrete properties were also studied
